Filed Nov. 9, 1935 3 Sheets-Sheet 3 Inventor L/Z/z/zewz/'S/ PatentedNov. 24, 1936 UNITED STATES PATENT GFFICE 6 Claims.

The invention relates particularly to a weatherstrip adapted to closecompletely the space between the bottom of a swinging door, windowframe,or the like, and the sill, floor, or other base with which such a partshould have a tight fit when closed.

It is an object of the invention to provide a Weatherstrip structurethat vwill push a laterally slidable packing-strip against the sill,oor, or equivalent part when the door or the like with which it isassociated is closed, and which will retract the strip therefromimmediately upon beginning of opening movement, whereby drag of thestrip on the sill, floor, or the like, will be avoided.

When considered with the description herein, the characteristics of theinvention are apparent in the accompanying drawings, forming parthereof, wherein an adaptation of the invention to a door is disclosed,for purposes of illustration.

Although the disclosures herein are considered to exemplify a preferableembodiment of the invention, it is to be understood that it is not theintention to be limited necessarily thereto in interpretation of theclaims, as modifications and adaptations within the limits of the claimscan be made without departing from the nature of the invention.

In the drawings, A designates a door, B the upright part of the frame orpost on which the door is hinged, and C the sill or floor below thebottom of the door, these parts being of usual and conventional form.

The device includes a housing, preferably` of sheet metal, formed with aplate or front wall I, a top II, and an upstanding flange I2 havingholes I3 through which suitable fasteners are driven into the door tosecure the device in place thereon. At each end, the material of thehous- 5 ing extends rearwardly as an end Wall I4 and thence inwardly asan inner wall I5 substantially parallel with the front wall or plate.The end walls afford mountings for an actuating bar, and the end andinner walls and the portions of the l0 front wall directly opposite thelatter constitute guides or slides for a packing-bar, as now described.

An actuating-bar I6, preferably rectangular in cross-section, ispositioned inside of the housing l5 and extends at one end through acorrespondingly shaped hole in one of the end walls, and on its outerend it has a head I'I. The other or inner end portion of the bar isformed with a longitudinal hole or bore I8. A guide-pin I9, mounted 20at one end on the other end wall of the housing, extends into the boreof the bar, and thus slidingly supports the inner end thereof.

A coil-spring 26, interposed between the inner end of the bar and theopposed housing-wall and disposed around the pin, urges the bar in adirection away from that wall and tends to protrude the headed end ofthe bar to its full extent.

A packing-bar 2|, below and substantially parallel with theactuating-bar, extends at its ends into, and is movable laterally in,the guides or slides at the ends of the housing. The packingbarpreferably is in the form of a metallic channel member, as shownparticularly by Fig. 6, which envelopes, clamps, and holds the upperportion of a packing-strip 22, and the lower portion of the stripextends downwardly therefrom. The packing-strip is of felt or othermaterial such as commonly used for like purpose in the weatherstrip art,but it is somewhat thicker than the strips ordinarily employed.

Links 23, one near each end of the device, are connected pivotally bypins 24 and 25, respectively, to the actuating-bar and packing-bar, thedisposition of the links being such that they are inclined to the barswhen the packing-bar is lifted or retracted in response to the urge ofspring 2E) forcing the actuating-bar outwardly (to the right whenviewing Figs. 4 and 7) and in response also to the urge of springs 26.

The latter springs are elongated ones tensioned to straighten, and theymay be spring wire as shown. Each of them has an end 21 extending underthe actuating-bar, between its ends it curves over an upper link-pin 24,and at its other end 28 it extends under the lower pin 25 of the samelink. With this arrangement of the springs 26, in which they aredeflected against tension from the straight condition, they exert adirect upward urge against the lower link-pins and thus against thepacking-bar.

The parts are proportioned and coordinated so that, when the packing-baris against the actuating-bar, and thus limited in its upward orretractive movement, the lower edge of the packingstrip is coincidentwith the lower edge of the front housing-plate l0, and thus the strip ishoused within the housing. This contact also limits the outward movementof the actuatingbar.

When the device is to be put on a door or the like, the packing-strip isheld at the outward limit of its movement, which is determinedvbycontact of the head Il of the actuating-bar with the adjacent end wallof the housing. This retention of the parts may be by any suitablemeans, for example by that shown by Fig. 9 The upper Wall l l of thehousing has a hole through which a pin 29 extends into a hole in theactuatingbar, these two holes being positioned to become aligned whenthe actuating-bar ispushed inwardly to the limit and thus thepacking-bar is protruded to its limit.

The head l1 of the actuating-bar I6 is in the form of a bumper-plate,which extends rearwardly and laps the edge of the door at the hingeside, as seen more particularly in Fig. 8.

With the packing-strip held outwardly by the pin 29, and the door beingshut, the device is placed against the lower side of the door, with thepacking-strip resting on the sill or floor beneath or pushed downthereagainst, and with the rearwardly extending portion of thebumperplate slipped into the crack between the edge of the door and theabutting surface of the doorframe structure. This easily determines theposition the device should have on the door, both with respect to thesill or :door and to the edge of the door and the surface of thestationary part opposite thereto. The device then is secured in place bydriving screws or other suitable fasteners through the holes in theflange l2'. The pin then is Withdrawn, whereupon the parts are free tofunction.

The parts are arranged and proportioned so that they remain in thosepositions until the door is nearly closed, when the head of theactuating-bar contacts with the side of the adjacent door-frame member.Thereupon, with the door continuing to swing closed, the bar is pushedinwardly, and, by the time the door is completely closed, thepacking-strip has been pressed, in protrusive direction, through theinstrumentality of thelinks, down against the sill or floor, and thus atight closure at the bottom of the door is afforded. o

As soon as the door begins to swing open, the actuating-bar begins to bereleased from its retracted position, the packing-strip begins to liftfrom the sill or floor and thus retracts to a position in which it doesnot contact with' and drag on the floor as the door continues to swingopen.

Ordinarily, the head of the actuating-bar will not mar or sink into thedoor-frame member against which it contacts, particularly if the frameis of hard wood. However, if it is necessary to protect the framematerial from the head, that easily may be done by driving a metalheaded article, such as a thumb-tack for example, as designated by 30,at the place of head contact.

The device is made in various lengths toconform to the widths of thestandard types of doors, swinging windows, and the like for which theyare intended.
